So I have been doing some digging and I am finding that people are often referring to the material they create in the editor as a shader. From my previous understanding, a shader defines how light reacts to things and a material defines what something should look like under light.
I realize these definitions might not be 100% correct (and any input on that would be appreciated) but my question is, why does it seem that many people are using “shader” to describe the “material” they are making?
